To be fair to
>>2, I think acknowledging the density of Pynchon's prose is a compliment to his writing ability, not meant as a negative point.
Personally, the first time I read Pynchon was on a bus driving through the city and after a couple of pages I had to stop and continue at home cause I couldn't give it my full attention. He writes with a rhythm that can look strange when you aren't in that frame of mind.
Elmore Leonard has a similar habit of writing like it's the spoken word. He omits words that don't change the meaning of the sentence when spoken, but in written form look like a typo. Once you are thinking like him, though, it's not hard to read.
